SA5.0CA Series
500 Watt Peak Power MiniMOSORB™ Zener Transient Voltage
Suppressors
Bidirectional*
The SA5.0CA series is designed to protect voltage sensitive components from high voltage, high−energy transients. They have excellent clamping capability, high surge capability, low zener impedance and fast response time. The SA5.0CA series is supplied in ON Semiconductor’s exclusive, cost-effective, highly reliable Surmetict axial leaded package and is ideally-suited for use in communication systems, numerical controls, process controls, medical equipment, business machines, power supplies and many other industrial/consumer applications.
Specification Features:
• Working Peak Reverse Voltage Range − 5.0 to 170 V • Peak Power − 500 Watts @ 1 ms • ESD Rating of Class 3 (>16 KV) per Human Body Model • Maximum Clamp Voltage @ Peak Pulse Current • Low Leakage < 1 mA above 8.5 V • UL 497B for Isolated Loop Circuit Protection • Maximum Temperature Coefficient Specified • Response Time is typically < 1 ns
Mechanical Characteristics: CASE: Void-free, Transfer-molded, Thermosetting plastic FINISH: All external surfaces are corrosion resistant and leads are
readily solderable MAXIMUM LEAD TEMPERATURE FOR SOLDERING PURPOSES: 230°C, 1/16″ from the case for 10 seconds POLARITY: Cathode band does not imply polarity MOUNTING POSITION: Any
